Embodiment Construction

[0024] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0025] figure 1 It shows the implementation flowchart of the image wide dynamic compensation method based on dual cameras provided by the present invention, which specifically includes the following steps:

[0026] In step S101, the first camera and the second camera are controlled to respectively lock the shooting target, and the first camera and the second camera are controlled to simultaneously shoot the shooting target to generate a first target image and a second target image respectively.

[0027] Wherein, the first camera and the second camera are arranged side by side close to one side of ...

Abstract

The invention relates to the technical field of image processing, provides an image wide dynamic compensation method and system based on double cameras. The method comprises following steps of controlling a first camera and a second camera to lock photographing objects; controlling the first camera and the second camera to photograph the photographing objects simultaneously, thus generating a first object image and a second object image; executing short exposure mode operation to the first object image, thus generating a first exposure image, meanwhile, executing long time exposure mode operation to the second object image, thus generating a second exposure image; carrying out image fusion processing to the first exposure image and the second exposure image, thus generating an object image. The generating time of the object image is greatly shortened; and the smearing phenomenon liable to be generated when a moving object is photographed is reduced.

Description

technical field [0001] The invention belongs to the technical field of image processing, and in particular relates to an image wide dynamic compensation method and system based on dual cameras. Background technique [0002] Wide dynamic technology is a technology used to allow the camera to see the characteristics of the image under very strong contrast. When high-brightness areas illuminated by strong light sources (sunlight, lamps, or reflections, etc.) and relatively low-brightness areas such as shadows and backlights exist in the image at the same time, the image output by the camera will appear bright areas that become white due to overexposure. However, dark areas become black due to underexposure, seriously affecting image quality. [0003] At present, the common wide dynamic compensation method is: use a camera module to continuously shoot three or more pictures, use different exposure times to perform short exposure, normal exposure and long exposure operations res...
